Definition / general
  • Rare; excellent prognosis
  • Mean age 30 years old, range 2-76 years
  • Tends to secrete estrogen / progesterone, but diagnose based on morphology, not hormones
  • Similar to a well differentiated Sertoli-Leydig tumor without a Leydig component; may have abundant cytoplasmic lipid
  • Associated with Peutz-Jeghers syndrome
  • Usually stage I and clinically benign (Am J Surg Pathol 2005;29:143)

Yellow and lobulated

Microscopic (histologic) description
  • Closely packed solid or hollow tubules lined by well-differentiated cuboidal to columnar epithelial cells
  • Few or no Leydig cells, often fibromatous or sclerotic; may have amyloid-like material
  • Other patterns include cord-like and diffuse; variable stroma
  • Occasional cells with bizarre nuclei; minimal mitoses, minimal atypia
  • Malignant: moderate to severe cytologic atypia and 5+ MF/10 HPF
